< resin bed 205 >
In this preferred implementation, the circumferential end wall 205d of resin bed 205 is arranged on the circumferential inside of the circumferential end wall 202e of sections 202 unshakable in one's determination.In addition, resin bed 205 is arranged to not occupy the space of inner surface 202f top of end wall 203c and the sections unshakable in one's determination 202 of insulator 203.
In addition, the delivery side face of resin bed 205 comprises the groove 205a that is arranged to hold neutral point busbar 250, and this neutral point busbar is with the Wiring member (that is neutral point) that acts on ground connection.Figure 28 is the stereogram that the groove 205a that is arranged in the stator sections 201 is shown.When stator sections 201 has been assembled together when limiting ringwise stator 200, the groove 205a of stator sections 201 is arranged to limit together the cannelure (see figure 2).Groove 205a and near the section it are shown in Figure 17.Figure 17 shows the situation that groove 205a has the neutral point busbar 250 that is arranged on wherein.In this preferred implementation, neutral point busbar 250 is annular or C shape Wiring member.12 neutral point terminal link 250a are attached to neutral point busbar 250.It should be noted that the quantity of neutral point terminal link 250a equals hop count.Each neutral point terminal link 250a all roughly is letter " T " shape, and is the same as the terminal component that is used for busbar unit 100 130.Each neutral point terminal link 250a all is fixed to neutral point busbar 250 by forging to wait.When stator sections 201 has been assembled together when limiting ringwise stator 200; Neutral point terminal link 250a is along circumferentially being provided with at interval with rule; Make every adjacent neutral point terminal link circumferentially spaced certain angle each other among the neutral point terminal link 250a, this angle is corresponding with the central angle of rear of core 202b.
Thereby each neutral point terminal link 250a all be arranged among the groove 205a with stator sections 201 in the terminal 204a of winding wiring of an independent stator sections in a terminal align.Neutral point terminal link 250a then is mounted to the terminal 204a of respective coil wiring.Figure 29 illustrates the sketch map that neutral point terminal link 250a is mounted to the situation of the terminal 204a of winding wiring.In Figure 29, neutral point busbar 250 is economized and is removed for convenience.Shown in figure 29, one among the terminal 204a of the winding wiring of corresponding stator sections 201 is inserted among each neutral point terminal link 250a vertically, makes the terminal 204a of neutral point terminal link 250a and winding wiring be electrically connected.
In addition, referring to Figure 28, the interior sidewall surface of groove 205a comprises a plurality of protuberance 205b.Protuberance 205b is arranged to prevent that neutral point terminal link 250a and neutral point busbar 250 from coming off.Referring to Figure 17, each neutral point terminal link 250a is maintained between the bottom of protuberance 205b and groove 205a.Protuberance 205b helps to prevent that neutral point terminal link 250a etc. from coming off from groove 205a.This helps further to guarantee the electrical connection between neutral point terminal link 250a and the terminal 204a of winding wiring then.
In addition, referring to Figure 21, resin bed 205 comprises par 205e, and this par is arranged on the delivery side of resin bed and makes that busbar unit 100 is mounted thereto.In addition, referring to Figure 17,21 and 22, resin bed 205 comprises the recess 205f at the radially inner corner portion place that is arranged on its delivery side.Stator 200 according to this preferred implementation is made up of 12 stator sections 201.Therefore, in stator 200, recess 205f is provided with the rule of 30 degree at interval.Each recess 205f includes the projection 205g that is arranged on wherein.In the hook 111 of keeper 101w one mechanically combines with projection 205g.According to preferred implementation of the present invention, recess 205f and projection 205g limit exemplary fixed part together.
< resin bed molded >
Figure 30 is the stereogram that the part of the mould 260 that is used for moulded resin layer 205 is shown.Figure 31 is the profile of mould 260.Figure 31 shows sub-component 206 and is arranged on the situation in the mould 260.Mould 260 comprises the 260a of fixed side mold portion, winding wiring end side mold 260b, the movable 260c of side mold portion and sliding part 260d.
Winding wiring end side mold 260b is arranged to locate this to the terminal 204a of winding wiring.Particularly, winding wiring end side mold 260b comprises that two are arranged so that the terminal 204a of winding wiring inserts hole 260e wherein.These two hole 260e are spaced apart at a predetermined distance from each other.This makes and to be assembled together when limiting ringwise stator 200 when stator sections 201 that the terminal 204a of the winding wiring of stator 200 is with the rule setting at interval of 15 degree (pitch angle=15 degree).Winding wiring end side mold 260b is provided with predetermined hermetically-sealed construction and spills through the gap between terminal 204a of any winding wiring and the winding wiring end side mold 260b (that is any hole 260e) with the resin that prevents to inject.
Sliding part 260d slides before injecting resin with the opposite shaft orientation end of sections 202 unshakable in one's determination (that is, an end) opposite with delivery side and contacts.
Next, will be described below the stage portion 203e of insulator 203 now.Can suppose that the 260a of fixed side mold portion has same size, this is because the identical 260a of fixed side mold portion is repeated to use.On the contrary, sections 202 unshakable in one's determination can have individual difference aspect axial dimension.Have under the situation of the axial dimension that reduces at sections 202 unshakable in one's determination, between the end wall 203c of the opposite shaft orientation end of the 260a of fixed side mold portion, sections unshakable in one's determination 202 and insulator 203, limit exceptional space.The resin that is injected into to limit resin bed 205 flows into this exceptional space.Have very little thickness if flowed into the resin of exceptional space, resin can be removed towards rotor 300 from the inner peripheral surface of stator 200 so.In order to prevent this from occurring, stage portion 203e is limited in the insulator 203.Resin flows into stage portion 203e when moulded resin layer 205.As a result, limited resin bed 205 has enough thickness.
The 260a of fixed side mold portion is arranged to extend along the medial surface 202f of the end wall 203c of insulator 203 and sections unshakable in one's determination 202, makes to prevent that resin bed 205 from extending beyond the medial surface 202f of end wall 203c and sections unshakable in one's determination 202.Referring to Figure 29, because the 260a of fixed side mold portion, the surperficial 205c that has flowed into the resin of stage portion 203e is arranged to flush with the medial surface 202f of sections 202 unshakable in one's determination.
In addition, the 260a of fixed side mold portion is arranged in both sides and contacts with the circumferential end wall 203d of insulator 203.In addition, the 260a of fixed side mold portion also is arranged in both sides and contacts with the circumferential end wall 202e of sections 202 unshakable in one's determination.That is to say that circumferential end wall 203d and 202e are as benchmark when moulded resin layer 205.Because the 260a of fixed side mold portion is arranged in both sides and contacts with the circumferential end wall 202e of sections 202 unshakable in one's determination, therefore prevented that resin bed 205 from extending beyond the circumferential end wall 202e of sections 202 unshakable in one's determination.
As stated, step is limited between the circumferential end wall 203d of circumferential end wall 202e and insulator 203 of sections 202 unshakable in one's determination.The 260a of fixed side mold portion comprises the corresponding step (each is measured as about 0.1mm) of step between the circumferential end wall 203d with the circumferential end wall 202e of sections 202 unshakable in one's determination and insulator 203.Therefore the step of similar size (that is, each is measured as about 0.1mm) is limited between the circumferential end wall 202e of circumferential end wall 205d and sections unshakable in one's determination 202 of resin bed 205.That is to say that the circumferential end wall 205d of resin bed 205 is arranged on the circumferential inside of the circumferential end wall 202e of sections 202 unshakable in one's determination.As a result, when stator 200 was assembled, the resin bed 205 of the adjacent stators sections of stator sections 201 was arranged to not circumferentially contact each other, and the circumferential end wall 202e of the adjacent sections unshakable in one's determination of sections unshakable in one's determination 202 is arranged to contact with each other.
Figure 32 is the coil 204 of the adjacent stators sections in the stator sections and near the enlarged drawing of its section.As stated, between the circumferential end wall 203d of the circumferential end wall 202e of sections 202 unshakable in one's determination and insulator 203, there is the step that is measured as about 0.1mm.Therefore, shown in figure 32, can guarantee to be measured as the air insulating layer more than about 0.2mm between the adjacent stators sections 201.Therefore about 0.1mm because the circumferential end wall 203d of each coil and corresponding insulator 203 separates each other guarantees the distance more than about 0.4mm between the adjacent copper wire in copper wire.
As stated, in this preferred implementation, the circumferential end wall 202e of the sections unshakable in one's determination 202 of stator 200 is arranged to contact with each other, and resin bed 205 is arranged to not circumferentially contact each other.Therefore can construct stator 200 according to the accuracy of having of this preferred implementation sections 202 unshakable in one's determination.Therefore, the situation that is used for constructing stator with stator sections that its resin bed is arranged to each other circumferentially contact is compared, and uses stator sections 201 structure stators 200 to help to realize the circularity improvement in the interior week of stator.Therefore because the circularity in the interior week of stator influences the characteristic of motor, can realize the characteristic improved according to the motor 1 of this preferred implementation.
In addition, the end wall 203c of insulator 203 comprises stage portion 203e.Stage portion 203e helps to absorb the accumulated error of the axial dimension of sections 202 unshakable in one's determination.
In addition, resin bed 205 is molded under the situation of terminal 204a by winding wiring end side mold 260b location winding wiring at this.This helps to guarantee to be limited at the sufficient accuracy of the pitch angle between the terminal 204a of winding wiring in each stator sections 201.This helps to prevent the short circuit (that is so-called phase internal short-circuit) between the terminal 204a of winding wiring in the same stator sections 201 then.In addition, make that busbar unit 100 is assembled to stator 200 is easier.The easy property of increase of assembling busbar unit 100 makes can use automation to assemble busbar unit 100.In addition, because the terminal 204a of winding wiring is suitably located, therefore can eliminate needs to the pressure wiring of electric wire.This helps to reduce the residual stress on the seam between the electric wire, and improves the reliability that is electrically connected.
In addition, busbar unit 100 mechanically is attached to stator sections 201 by the recess 205f of stator sections 201.This helps to improve mechanical rigid, vibration resistance and the impact resistance of busbar unit 100.
In addition, each stator sections 201 includes groove 205a, and this groove 205a is arranged to hold neutral point busbar 250 independently with busbar unit 100.The situation that is arranged on single busbar unit with electric wire that is used for every phase and the electric wire that is used for ground connection is compared, and this helps to reduce the length overall of motor 1.This helps to realize reducing cost then.
In addition, resin bed 205 is arranged so that coil 204 is folded between insulator 203 and the resin bed 205.This helps to reduce the excited vibration of coil 204.
It should be noted that in other preferred implementation of the present invention, the aforementioned dielectric layer can be limited by coating (that is electrolytic deposition coating) rather than insulator 203.
Should also be noted that neutral point busbar 250 can be through being gone out annular or C shape part is produced by plate stamping.In this case, when neutral point sink stream bar 250 was gone out by plate stamping, neutral point terminal link 250a can limit with neutral point busbar 250 integratedly.
The hop count that should also be noted that stator former 200 only is an example.
Should also be noted that being limited at these above-mentioned number of degrees to the central angle between the terminal 204a of winding wiring only is example.That is to say, be limited at this central angle between terminal 204a of winding wiring can be as in the above-mentioned preferred implementation be half of the central angle of sections 202 unshakable in one's determination.
[structure of rotor 300]
Shown in Figure 33 and 34, be rotor with two-part side rotation structure according to the rotor 300 of this preferred implementation.Rotor 300 comprises rotor core 310, magnet 320, distance piece 330, rotor cap 340 etc.Rotor core 310, magnet 320, distance piece 330 combine by rotor cap 340 reliably, and do not use adhesive.It should be noted that Figure 34 shows this rotor cap 340 (that is base portion 340a) before collar part 341 is limited in the rotor cap 340.
The quantity that is included in according to the rotor core 310 in the rotor 300 of this preferred implementation is two.Each rotor core 310 all is the cylindrical components with the cross section that roughly is the octagon shape.Rotor core 310 comprises the through hole 311 that is limited to its center.Through hole 311 is arranged to roughly coaxial with rotation S, and is arranged to have the axle 6 that is fixed therein.Rotor core 310 is limited a plurality of metallic plates stacked up and down along rotation S and that be combined into single main body.
Each all has two rotor cores 310 of the magnet group that is attached on it and arranges up and down along rotation S.Every pair of rotor core 310 will be called as " rotor assembly 301 " with the magnet group.Two rotor assembly 301 are assemblied in the rotor cap 340, make rotor assembly 301 circumferentially be shifted each other and are scheduled to step angle.Therefore each magnet in eight magnets 320 in each rotor assembly 301 all with another rotor assembly 301 in eight magnets 320 in a corresponding magnet circumferentially displacement be somebody's turn to do and be scheduled to step angle.In other words, rotor assembly 301 has segmentation side rotation structure.
The quantity that is included in according to the distance piece 330 in the rotor 300 of this preferred implementation is two.Each distance piece 330 all is to have roughly ringwise and the member of a part of being arranged to extend along the inner peripheral surface of rotor cap 340.Distance piece 330 is arranged to make its external diameter to be slightly less than the internal diameter of rotor cap 340.In addition, distance piece 330 is arranged to make its internal diameter to have the diameter greater than through hole 311.The external diameter of distance piece 330 is arranged to the external diameter less than rotor core 310 at least.It should be noted that distance piece 330 can be processed by metal or resin, as long as it is processed by nonmagnetic substance.
Each distance piece 330 all is arranged between the end face and one of them collar part 341 of the independent rotor assembly in the rotor assembly 301 that is assemblied in the rotor cap 340.Each collar part 341 all is out of shape through the end that makes rotor cap 340 and is limited.Each distance piece 330 all is arranged to combine to limit with corresponding collar part 341 axial motion of corresponding rotor assembly 301.And distance piece 330 helps to be convenient to process collar part 341, and helps to prevent that magnet 320 and rotor core 310 are damaged during processing.Below its details will be described.
Rotor cap 340 is the tubular metals that stand metal processing.Rotor cap 340 comprises tubular perisporium 342 and opening 344, and the place, two ends that this opening 344 is arranged in rotor cap 340 opens.Rotor cap 340 limits through tubular and the processing of jointless base portion 340a withstanding pressure are waited.Rotor assembly 301 is placed in the rotor cap 340 with distance piece 330 by each opening 344 and is mounted to rotor cap 340.Each rotor assembly 301 is all by interference fit rotor cap 340.Rotor cap 340 is arranged to protect rotor assembly 301 and distance piece 330, and suitably the location with keep rotor assembly 301 and distance piece 330 integratedly, and do not use adhesive.
Except that rotor cap 340 comprised the collar part 341 that is limited to wherein, rotor cap 340 was substantially the same in base portion 340a.The part around each opening 344 of base portion 340a (also being called " processing edge 345 " hereinafter) by the collar part 341 of radially radially inwardly giving prominence to qualification to internal strain, makes rotor cap 340 be done.Therefore the axial dimension of base portion 340a is designed to line shaft greater than rotor core 310 and magnet 320 to size.
The outer surface of the perisporium 342 of rotor cap 340 comprises the recessed separating part 350 that radially inwardly is pressed into.This recessed separating part 350 is corresponding with the gap of being arranged to along between rotation S two rotor assembly 301 adjacent one another are.Recessed separating part 350 according to this preferred implementation is limited along the straight trough that circumferentially extends at the axial centre place that is arranged in rotor cap 340.Recessed separating part 350 helps to keep two rotor assembly 301, makes these rotor assembly 301 not contact with each other.
It should be noted that the structure of rotor cap 340 can be modified, as long as avoid the contact between the rotor assembly 301.That is to say that the gap that is limited between the adjacent rotor assembly 301 by recessed separating part 350 can only be small.Note, yet, when rotor assembly 301 be configured to each other too near the time, the high speed rotating of rotor 300 possibly cause occurring eddy current loss.Therefore preferably, recessed separating part 350 be arranged to make two rotor assembly 301 separate each other 1mm or more than.
The outer surface of the perisporium 342 of rotor cap 340 comprises a plurality of grooves 346 that are limited to wherein.Groove 346 is arranged to extend along rotation S with magnet 320 corresponding mode.On the both sides of the recessed separating part 350 in rotor cap 340, groove 346 is arranged in either side and does not extend beyond the end.
Each groove 346 includes and is arranged on the first end wall 346a that it is more located near the end of opening 344.The first end wall 346a is arranged to radially inwardly generally perpendicularly extend from the outer peripheral face of rotor cap 340.The first end wall 346a edge of groove 346 is circumferentially roughly along the straight line setting.Simultaneously, each groove 346 more has taper near the end at an end place of recessed separating part 350.Each groove 346 is more comprising the second end wall 346b near this end at an end place of recessed separating part 350, and this second end wall 346b is arranged to tiltedly extend from the outer peripheral face of rotor cap 340 is radially lean-in.It should be noted that the shape of the second end wall 346b is when limiting groove 346, to avoid forcing the result who removes base portion 340a from column anchor clamps 360.
Referring to Figure 35, because groove 346, rotor cap 340 comprises a plurality of support regions 347, and each support region all has the cross section that is the minor arc shape.Each support region 347 all is arranged to the radially outward outstanding convex surface 321 that is assemblied in the independent magnet in the magnet 320 in the rotor cap 340 with coupling.In other words, each magnet 320 is arranged so that the independent support region in its convex surface 321 and the support region 347 is oppositely arranged.In addition, each magnet 320 all is arranged to contact with corresponding support region 347.Therefore each magnet 320 all is limited circumferential movement, and is maintained at the precalculated position.
Along between per two support regions 347 circumferentially adjacent one another are, limit recess 348, this recess 348 is line along rotation S and extends and link to each other with two support regions 347.Form contrast with support region 347, each recess 348 all is arranged to radially inwardly outstanding to have the cross section that is the minor arc shape.Recess 348 is to embed to be limited at the dolly dimple in the gap between per two adjacent magnets 320.Each recess 348 all is arranged in the circumferential middle part of the independent groove in the groove 346.In addition, recess 348 be arranged to from the first end wall 346a extend to the second end wall 346b near.Recess 348 helps to prevent reliably the contact along between any magnet 320 circumferentially adjacent one another are.
Each support region 347 all be arranged to magnet 320 in the convex surface 321 tight faces of an independent magnet contact.This helps suitably to keep magnet 320.
Particularly, referring to Figure 36 A and 36B, the inner surface of support region 347 is arranged to make the radius of curvature of its radius of curvature less than convex surface 321.The size of the part of rotor cap 340 is designed such that two two circumferential inside of circumferentially holding of circumferentially holding the inner surface that is positioned at corresponding support region 347 of the convex surface 321 of each magnet 320.
Referring to Figure 36 A, when not having external force to be applied to support region 347, the radius of curvature of support region 347 is less than the radius of curvature of convex surface 321.Therefore, when convex surface 321 contacts the inner surface of support regions 347, two unitary part contact convex surfaces 321 near its two circumferential ends of support region 347, and the pars intermedia of support region 347 does not contact convex surface 321.Referring to Figure 36 B, after rotor core 310 grades were mounted to base portion 340a, power was applied to base portion 340a, like the diameter that increases base portion 340a.As a result, two of support region 347 circumferential end are drawn along mutually opposite direction.As a result, being applied to support region 347 towards the acting power of rotation S is positioned on the magnet 320 to force support region 347.With this mode, the inner surface of support region 347 is all contacted basically with convex surface 321 realization faces.
And, when support region 347 closely contacts convex surface 321 when having the identical radius of curvature of radius of curvature with convex surface 321, have this radius of curvature and the arc length that limits support region 347 in the arc that has this radius of curvature and limit on convex surface 321.This helps to guarantee the face contact between convex surface 321 and the support region 347.As a result, magnet 320 is suitably circumferentially located.
Referring to Figure 37 and Figure 38, will be described below the mathematical equation of radius of curvature of being used to derive support region 347 etc. now.Suppose that Ra representes the radius of curvature (mm) of this support region when not having external force to be applied in support region 347, and α representes the central angle (radian) of support region 347.Suppose that similarly Rb representes the radius of curvature of recess 348, and β representes its central angle.
Suppose Ra ' expression support region 347 radius of curvature of this support region when being out of shape when be mounted to rotor cap 340 in magnet 320 grades after, and α ' representes its central angle.Suppose Rb ' expression recess 348 radius of curvature of this recess 348 when being out of shape when be mounted to rotor cap 340 in magnet 320 grades after similarly, and β ' representes its central angle.It should be noted that Ra ' equals the radius of curvature of convex surface 321.
Suppose that R representes the maximum outside diameter (mm) of this rotor cap when magnet 320 grades have been mounted to rotor cap 340.Suppose that also θ representes the central angle of a utmost point of rotor 300, t representes the thickness (mm) of rotor cap 340, and L representes the girth (mm) of rotor cap 340, and E representes the Young's modulus of rotor cap 340.
When rotor cap 340 was constructed in the above described manner, following geometric equation was set up.
α '=θ+β ' equation 1
(R-t-Ra ') sin θ=(Ra '+the sin β ' equation 2 of Rb '+t)
In addition, when magnet 320 grades have been mounted to rotor cap 340, produce tensile force f at the circumferential end place of support region 347 and recess 348.Support region 347 is extended with recess 348 thus, makes following equation set up.
The tensile force f that produces at support region 347 places produces and acts on the radially internal force N (that is supporting force) on the magnet 320.Supporting force N is represented by following equation.
N=2Fsin (α '/2) equation 4
Therefore, through making the supporting force N that calculates based on aforesaid equation, guarantee the suitable maintenance of magnet 320 greater than the maximum centrifugal force that is applied to magnet 320.
Particularly,, guarantees following inequality the suitable maintenance of magnet 320 when setting up:
N>MmRmS
2Equation 5
Wherein Mm representes the quality of each magnet 320, and Rm representes from the center of through hole 311 to the distance of the center of gravity of magnet 320, and S representes the maximum angular rate based on the rotor 300 of its design.
< making the method for rotor >
Next, will be described below method now according to the manufacturing rotor 300 of this preferred implementation.
As stated, under the situation of not using adhesive, magnet 320 grades are assembled to rotor cap 340 and so that construct rotor 300 with the mode of one.Particularly, magnet 320 grades are assembled to rotor cap 340 so that the method for constructing rotor 300 with the mode of one comprises the steps: to limit the step (that is, base portion limits step) of the base portion 340a of rotor cap 340; Limit the step (that is, recessed separating part limits step) of the recessed separating part 350 among the base portion 340a; Limit the step (that is, support region limits step) of the support region 347 among the base portion 340a; Rotor core 310 and magnet 320 are assembled to the step (that is installation step) of base portion 340a; And the step (that is, collar part limit step) of the collar part 341 among the qualification base portion 340a to accomplish rotor cap 340.
(base portion qualification step)
Referring to Figure 39 A, 39B, 39C and 39D, the base portion 340a (initial condition) of rotor cap 340 limits in the step at base portion and is defined.Particularly, referring to Figure 39 A, at first withstanding pressure processing is limiting the pressed metal article for metallic plate, and these pressed metal article have bottom and tubular and do not have seam roughly.See that from the angle of durability and motor performance the thickness of metallic plate is preferably in the scope of the extremely about 0.3mm of about 0.2mm.
